IPC: C07C323/22
Filed: 1981-11-18
Abstract: PURPOSE:To prepare the titled compound useful as an agricultural chemical and its intermediate, in high yield, economically in an industrial scale, by hydrolyzing a cyclopentenone compound. CONSTITUTION:A cyclopentenone compound of formulaI(R is lower alkyl; R1 is H or lower alkyl; R2 is H, lower alkyl, lower alkenyl or lower alkynyl) is hydrolyzed in a solvent such as THF in the presence of an acid or an alkali at -20-+120 deg.C to obtain the objective compound. Water is an essential component of the solvent for hydrolysis. It is necessary to use >=1mol of water per 1mol of the raw material, however, a large excess water is usually used in combination with the solvent. EFFECT:The addition of the catalyst is effective to increase the rate of reaction and improve the conversion. The catalyst is, e.g. a quaternary ammonium salt.

Title: Image forming method
Inventor: SATOMURA MASATO
IPC: G03F7/32
Filed: 1987-07-27
Abstract: PURPOSE:To obtain the high sensitivity of an image comparing with a photopolymerization reaction using a photopolymerization initiator by developing a photosensitive material in the presence of a polyvalent metal salt. CONSTITUTION:The photosensitive material is developed in the presence of the polyvalent metal salt. Said salt is concretely exemplified by a two or tri valent salt of a metal such as barium, lead, copper, cerium, iron, cobalt and nickel, etc., and is enumerated by a salt of an inorg. acid such as chloride, sulfate, nitrate and phosphate, etc., or a salt of an org. acid such as oxalic acid, tartaric acid, acetic acid and toluenesulfonic acid. As only a little amount of said polyvalent metal salt is sufficient at the time of developing, said salt may be incorporated in the photosensitive material or in a developer. When the photosensitive material is developed with the developer, said compd. may be incorporated in the developer. The compounding amount of said compd. in the photosensitive material is about 1-10<-5>mol., preferably, about 0.1-10<-4>mol. per 1mol. of silver halide. Thus, the sensitivity of the photosensitive material is remarkably improved.

Title: Element substrate of liquid crystal display device
Inventor: TAKAHASHI SHIROU
IPC: G02F1/133
Filed: 1987-07-27
Abstract: PURPOSE:To improve display performance by preventing the picture element electrode connected via a specific timing line and 2-terminal element from coming into contact with the timing lines except the specific timing line. CONSTITUTION:This substrate is so constructed that the picture element electrode 3 connected via the n-th timing line and the 2-terminal element 4 is enclosed by the n-th timing line 1 to prevent the picture element electrode 3 from coming into contact with the timing lines, except the n-th timing line, more specifically the (n-1)th timing line. The (n-1)th timing line 2 becomes the n-th timing line 1 in this case and the writing between the n-th timing line 1 and the (n-1)th timing line 2 is forbidden. Consideration is eventually required only for the writing between the n-th timing line 1 and a data line 6. The signal sufficiently controlled by an impressed signal is thereby impressed on the picture element electrode and the sufficient display performance is obtd. Since the generation of a defect by a disconnection, etc., is substantially obviated, this substrate is effective for the enhancement of the image quality.

With above process, no intermediate layer exists and the position of the PN-junction can be determined considerably freely. Practically the parameter is only one, which is the carrier density of the multiplication layer, so that significantly high degree of freedom can be obtained.

IPC: B66B1/28
Filed: 1993-06-29
Abstract: PURPOSE:To smoothly start elevation of an elevator and stop it at an accurate position by detecting an output shaft rotation speed and elevating time or elevating position for switching from an auxiliary motor to a main motor, and starting low speed reduction ratio rotation of the output shaft by means of the main motor in idle rotation. CONSTITUTION:In a driving device 1, a main motor 3 and an auxiliary motor 4 are arranged on both sides of a reduction gear 2. An output shaft 22 is rotatably provided extending in the fore and aft direction and orthogonally crossing an input shaft 20, in a case 26 of the speed reduction gear 2. A take-up drum of an elevator is fitted to a protruding part of the case 26 of the output shaft 22. When the output shaft 22 reaches a specified rotation speed, specified time is elapsed, and the elevator reaches a specified position, switching between the main motor 3a and the auxiliary motor 4 having different speed reduction ratios slowly starts the output shaft 22 of the driving device 1 to change-over regenerative brake of the auxiliary motor 4 to an auxiliary speed reduction gear 6 for slow stopping. Accordingly, accurate stopping is conducted regardless of load or no-load of the elevator.

Title: Scavenging port in two-cycle diesel-engine
Inventor: ISHIDA HIROYUKI
IPC: F02F1/22
Filed: 1992-06-23
Abstract: PURPOSE:To smoothly push up combustion gas in a cave in the upper surface of a piston so as to enhance the scavenging efficiency by inclining the center lines of scavenging ports in an upper one of upper and lower scavenging port rows, at an depression angle with respect to the center line of a cylinder. CONSTITUTION:When combustion gas pushes up a piston 31 so as to open an exhaust valve, exhaust gas is discharged so that the internal pressure of the cylinder is lowered. Thereafter, during a scavenging process from the time when the upper surface of the piston 31 downwardly passes over the upper edge of an upper scavenging port 21a, to the time when the upper surface of the piton 31 upwardly passes over the upper edge of the port 21a after passing through the bottom dead center, fresh air flows into a cylinder liner through an area defined by the scavenging port outlet at the inner surface of the liner and the upper surface of the piston 31. The inflow fresh air receives a component in a swirl direction, and further, receives a downward velocity component due to a depression angle beta in the upper scavenging port 21a, and accordingly, it is introduced along a cave in the upper surface of the piston 31. Accordingly, it is possible to exhibit such an effect that combustion gas in the cave of the piston is pushed up, thereby it is possible to enhance the scavenging efficiency.

Filed: 1986-08-08
Abstract: PURPOSE:To detect transparency on a transfer drum by driving a detecting means while endlessly moving a recording material holding transfer body prior to the transfer of a developed image to a recording material, and then detecting the recording material holding state of the transfer body. CONSTITUTION:The transparency (a transparent polyester resin sheet) is held by a transfer drum 20. Jam detection is impossible on a V-shaped part from the leading end of the transparentcy up to transfer paper corresponding to the final end because the transparency at that part is transparent, and jam detection can be possible in a part 2 of the transfer paper. Since the leading end of the transparency is located on a transfer position when jam detection can be available, an image does not coincides with the leading end of the transparency even if image formation is executed immediately after detection. Thereby, the transparency is sent to the drum 20, the drum 20 is excessively rotated prior to the formation of the image to detect the transparency. Thus, the transparency can be detected on the drum 20.
